Exhibits:Pi Day: Liberty Science Centre,PlayTech

Interactive visual installations representing the mathematical constant π, its use from simple colors on the screen to advanced graphics, from natural forms to forces that operate on them.

The visual projections are created using code [GLSL shading language, ISF, VDMX, TouchOSC] and candy. Each projection is composed of 3 interactive animated layers - color gradients, shapes/noise and an object from nature.

Projection 1
- Beautypi by iq
- Hypnotic ripples by cha
- [SIG2014] by dynamite

Projection 2
- Sunset on the sea by h3r3
- Playing with FBM by Lallis
- PinkWaves by UNDERDOGKID91

Projection 3
- Marble Fantasies by tholzer
- smoke by me
- purple by me

The code of each layer was modified by extracting parameters that influence different equations and interactive versions were created using ISF, that could be blended and projected via VDMX.

The user interface was created using TouchOSC for all projections in an app with a XY pad for position, 6 rotary sliders for custom effects and a fader control for each layer. The app connects wirelessly to VDMX using Osculator. An iPad was used to run the app which significantly improved the interface interaction experience compared to the earlier prototypes that used game controllers instead.

Using the iPad, users can manipulate different parameters in the projections inside a 12-foot geodesic dome (made out of cardboard) to change space, time, dimensions, colors and more. The visuals are spherically projected inside the dome using 2 short throw projectors and Matrox TripleHead2Go with carefully curated sounds as accompaniment.
